The first pre-production Challenger 3 Main Battle Tank has been deployed to Germany for trials.

During the trials, the prototypes will be tested under operational conditions to validate their performance and refinements before another 140 are built and delivered to the British Army.

The Challenger 3 platform will be fitted with a new 120mm L55A1 smoothbore gun built by Rheinmetall, enabling the use of the most advanced ammunition available. Next Generation UK-sovereign modular armour, a fully digitised turret and integration of Trophy Medium Variant APS onto the platform will protect against rocket propelled grenades and anti-tank missiles.

The above is a brief sumamry of what is involved in coverting tanks to ‘Challenger 3’ standard.

Challenger 3 Deputy Project Manager at RBSL, Nick Berchem said:

“Designed with the crew’s safety, operational effectiveness, and comfort at its heart, and with the users’ advice at every stage, I am sure it will prove to be a very potent and popular addition to the British army’s inventory. It is hugely exciting and very satisfying to be part of the team bringing this immensely capable tank to life.”

RBSL is playing a key part in delivering the Land Industrial Strategy through its Challenger 3 programme, ensuring it benefits from the best of British engineering and manufacturing, whilst also sustaining valuable skills across the country.

Colonel Will Waugh, Senior Responsible Owner of the Army’s Armour (Main Battle Tank) Programme, said:

“Delivery of the first pre-production Challenger 3 and the commencement of trials marks a critical milestone on the journey to the Army’s modernised Main Battle Tank capability.  Challenger 3 will be at the heart of the Army’s Armoured Brigade Combat Teams, alongside Ajax and Boxer, under Future Soldier.  Events in Ukraine have underscored the need for credible warfighting capabilities. The Army’s Armoured Brigade Combat Teams, with Challenger 3 at their centre, are key to the UK’s contribution to NATO’s deterrence.”

Major General Darren Crook, Director Land Equipment for Defence, Equipment & Support said:

“In an increasingly uncertain and dangerous world, our priority is to deliver to the Army the capability it needs to deliver Future Soldier and be more lethal on the Battlefield. I am immensely proud of the work the whole team has undertaken: the Army, DE&S and RBSL working together to deliver  the first pre-production Challenger 3. This marks a critical milestone in our delivery of this impressive capability to the British Army and will provide our soldiers with a world-class Main Battle Tank made here in the UK. It also demonstrates the centrality of the Land Industrial Strategy, with the UK increasingly developing a highly-skilled industrial base and maintaining strategic advantage through our Industry partners such as RBSL.”

  1. Is it still 148 in total ? the article seems to suggest one prototype and another 140 to follow…… Hope they all get the Black Paint Job ….. they do look rather menacing in black.

          • We have a history of selling old tanks to Jordan, but they are receiving ex-UAE Leclercs by way of replacement. After CR3 conversion, how many good-ish CR2s will be left to sell or gift? Not too many, I suspect.

          • I’ve wonder if the Jordanian C1 could be candidates for upgrades should we need numbers in hurry. The C3 turret was supposed to be versatile so it could be fitted to other NATO tanks, not sure how portable the other upgrades would be to a C1. I appreciate its not an ideal upgrade, but where else are there 400 tanks UK could access easily and at short notice. And if you can shoehorn in the same powerpack/transmission, turret, APS, radios, targeting system etc you create a high level of common parts. And whilst the armor is behind the C3 its still very effective especially with reactive armor on top and APS. Using a strategy from the 1930’s prepare for war, so get a C1, prototype the upgrade and test the upgrade, identify who will do the upgrade (ie shadow factory concept) then you have a prepackage upgrade ready to go and can execute if needed. We started WW2 with less tanks than Germany but our preparations and ability ramp up production was a far more important factor than the number we started with.

            It would make sense to store the remaining C2 knowing there’s pre packaged proven upgrade that could be applied should we need it.

            Of course the best option would be a new tank but that’s very unlikely to happen.

          • There are certainly worse ideas, but it would be expensive and time consuming returning even a portion of those 40-year-old tanks.

            Better to spend the money and effort accelerating Challenger 3, expanding the order to at least 200 (and preferably the full 400+ fleet, or whatever is left of it), and identifying what will come after.

            The question of whether heavy armour still has a place on the battlefields of the future needs to be answered before we start pushing for a new BAOR. Would drones and a heavy gun for Boxer or Ajax make more sense? Who knows

          • With you Callum. 200 seems like a good pool for such a major asset for 4 tank groups plus a smaller reserve. I know nothing on this it’s just a gut feel and seems a shame that they let the numbers deteriorate to just 148.

          • It was more of an outside the box thinking based on rearming quickly. Personally I think building or upgrading 100s upon 100s of tanks which may sit in storage is not the best plan. But if you’ve done the ground work to upgrade or build from new, tested the design, identified who will build, who all the suppliers are etc Then your in good position to ramp up production. And arguably in better position than having 400 tanks with no plan to produce more.

            This is not a new concept in the 1930s we identified factories that would switch to military production if needed. That turned out to be more important than having more tanks than Germany when war broke. We were soon out producing Germany who struggled to replace what they had.

          • The Jordanian CR1 conundrum was discussed at great length on what is now X – according to those in the know it is likely that enquiries were made about the status of the fleet but nothing came of it.The exact reason wasn’t given but it was narrowed down to either the Jordanian Govt not willing to play ball and release them for refurb, or the poor material state of them meaning it would not be cost effective.TBH it may have been a combination of the two but the facts will come out in time.

          • I’d be surprised if the Jordanians didn’t want to gift them, we gifted them in the first instance. Probably there was better options throughout Europe. It was unlikely to be just UK paying to bring these back into service and with various other tanks more readily available better to focus attention elsewhere.

          • I was the MoD Equipment Support Manager for CR1 after it had been wirthdrawn from service and folowed my predecesssor by finishing off the disposals – most went to Jordan as you know. You are talking about a vehicle that was devloped from the Chieftain with design work done in the 1970s, built c.1982-1990, in-service with UK 1983-2001, sold to Jordan and in service with them 1999-2022. Jordan has replaced them with ex-UAE Leclerc and ex-Italian Centauro whelled tank destroyers.

            So now take a tank that has done service over 40 years and been pensioned off by first and now second user – and give it a new lease of life for the British Army! That’s not going to fly. Some suggested that Jordan might like to gift those 400 tanks to Ukraine, pretty much as is, but with a quick, basic and cheap refurb (but that didn’t happen).

            MoD does not have the cash to produce any more than 148 CR1s so how could they be persuaded to upgrade 400 CR1s to CR3 as well – but if they did, then what – store them – where – no room at Ashchurch for that number of additional tanks – who would crew them in time of war – we don’t have 400 spare tank crews (ie about 7 armoured regiments of manpower – or would they all be used for the most massive Attrition Reserve?

            I would much rather maximise CR3 numbers from more CR2 donor vehicles (in fact convert every CR2 that we have that can meet the Minimum Acceptable Presentation Standard) for which there is an established engineering programme. Retain the third armoured regiment that we have today. Boost the Attrition Reserve. But all this costs big money and requires additional manpower to be added back, so it probably won’t happen.

          • Lots of good sense Graham. I suppose the UK can’t ask for their gifted Ch2s back, to bolster numbers and have them replaced by Leopards or others? Or the UK order a Leopard tank batch (40) for themselves? It’ll be a mixed fleet but interoperability with lots of European allies.

          • What!? That would be terrible for the Ukrainians – they are getting very good use out of their 13 CR2s as ‘sniper tanks’ – they absolutely love them. It would be the biggest diplomatic fail you could imagine to ask for them back

            Why would we want 13 CR2s to be returned? What for? What has suddenly happened since we judged we could spare them. Are our needs greater than Ukraine’s?

            We have 213 active list CR2s [plus a good number (maybe 100-117) on the inactive list (probably in bad condition)].

            We need to give 148 tanks to RBSL in batches between now and 2030 for the CR3 upgrade. Thats do-able whilst keeping a good number of CR2s back for the soon-to-be two armoured regiments, trg org etc.

            Why do we want a tiny fleet of Leopard 2 (not enough for one ard regt), when we have CR2 and are getting CR3?

          • It was just a hypothetical but as you say it isn’t really justifiable and not a good like either so it’s okay to cancel my silly suggestion ..lol. Have to admit your Ch2 numbers do suggest that pool is quite a bit bigger than the 148 Ch3’s so there’s room for more Ch3’s if the need arises and the monies are there.

          • Are some people thinking we will only upgrade 148 tanks because there are only 148 CR2s? Surely not. We have 213 CR2s on the active list (was 227 – that figure published for the last 14 years – but gave 14 to Ukraine early last year) and more on the inactive list.

            Up to recently 43 of the 386 tanks originally purchased have been scrapped (sometime in the 2010-2014 period, for reasons unknown), but MoD recently declared that a handful more (4 or 5?) have been scrapped. Not sure if more have been scrapped over the period 2014 -2023 but not been declared publicly.

            Pedantically, I think the term ‘scrapped’ is being used incorrectly – I am sure they mean that such tanks have been categorised as Beyond Economic Repair (BER) as I have not heard of any scrap metal merchants turning up to Ashchurch!

            I think the need for more than 148 tanks (just two armoured regiments) is clear (after all, the army decided upon and bought 386 tanks to meet the post-Cold War requirement after the Options for Change defence review). But the money is not there!

          • I’m not suggesting we actually upgrade 400 c1s now. But instead like we did in the 1930 have a plan to up arm quickly should hostilities commence. As you say its expensive to have 400 tanks ready to roll. But if you have reached a point where we have proven path to get a tank into production or upgrade then you massively shorten the time to get it rolling off the production lines.

            War is won by being able to out produce your enemy and right now my concern is we have no plan to be able to rearm at pace.

            Germany had more tanks at the start of WW2 but its ability to replace was woeful.

            Maybe 400 c1s aren’t the best plan as you say they maybe too far gone, but I sincerely hope our political class actually has a plan.

          • We certainly need a rearmament plan.

            To take just the tank example for now: We could start by upgrading many more than 148 CR2 tanks to the CR3 model.
            We have 213 tanks on the active list and maybe 100+ on the inactive list (which will be in poor shape with many parts lost to cannibalisation) but they should be assessed for suitability and maybe we could make 2 tanks out of 3 ie get a further 60 or 70 to an acceptable presentation state for upgrade to CR3. Thus we might be able to push another 120 or 130 to the RBSL build line on top of the 148 contracted for. This is speculation as I do not know for sure the number of tanks on the non-active list or their condition.

            268 or 278 tanks would be enough for a well resourced division with a reasonably sized attrition reserve. To send more armour than one division (ie to resource more AS90s, Warriors, B vehs etc etc) would be beyond our capability.

          • I guess the biggest issue is hull stress, anything that a can be unbolted can be replaced(in theory). But cracks in the hulls need to be properly assessed, this would require stripping the Hull then putting it through a non destructive tests NDT to detect cracks and fractures. Then assess if these can be repaired. If there’s known stress failure points, then these could be reworked without testing.

            Are all the C2s stored in an environment where corrosion isn’t an issue.

            There’s one further source if C2s, Oman has 38 I believe. I assume we’re offering a C3 upgrade but if that doesn’t fly then, depending on the condition, repurchasing them could be an option. I have no idea what condition they’re in.

            Another factor is if the war in Ukraine carries on and Oman is looking to replace them they could end up.being repurchase and sent there.

          • I don’t know if Babcock who now operate the former 18 Base Wksp REME/ABRO Bovington site do Base Overhauls or similar on the entire UK tAFV fleet – I would hope they did. In the days when this was done by in-house personnel, then every square inch of the stripped out hull was carefully looked at especially the welds using NDT. Re-welding was done if required. This was all standard procedure.

            Are all CR2s in CHE? – I doubt it. You must assume Defence is well-resourced! Some CHE exists at BATUS, Ashchurch and at least one of the two depots in Germany. Pretty sure no CHE exists for tanks (or other AFVs) in the Field Force or the Trg Org. Where CHE exists at the afore-mentioned places it is by no means certain that any or all CR2s located there are in it. Other kit may be in the CHE. I just don’t have that info.

            You seem keen for us to get more CR2s – not sure why. Even if HMG increases the number worked to CR3 standard up to 200 (very unlikely), then there are sufficient donor tanks on the active list (ie 213) without buying the Omani tanks. They don’t have to be in fabulous condition before sumbmission to the RBSL CR3 build line, just up to the Minimum Acceptable Presentation Standard (don’t ask me for the definition – of course, I don’t have that).

          • I’m not assuming there’s additional resources but like airframes you only fly airworth airframes. I would hope the Army has a minimum standard. The good news fro. What you’re saying is we should have a very good appreciation of where the C2 hulls get stressed.

            I’m not desperate to get more C2, my thinking is along the same lines as previous comments. We have a ready to go upgrade for C2s so if we have access to them we can get nearly 40 C3 tanks quickly if we needed to.

          • Thanks. The Minimum Acceptable Presentation Standard (MAPS) is nothing to do with routine operation of the tanks – it is a standard specifically relating to suitability of a donor vehicle for a major upgrade such as conversion to CR3. For example it would not matter if certain assemblies, sub-assemblies or components are missing or do not work if those are to be replaced by new items in the upgrade. Theoretically a tank could possibly be missing its entire turret! [Although I have not seen the MAPS document for this work, of course]

            In routine operation of CR2 very different criteria are applied – you’ve got to be able to use the thing – and in my day a tank was either battleworthy, fully fit – or is unserviceable (and needs work by crew and/or REME).

            Sadly I remain sceptical that HMG will sanction more than 148 tanks to be upgraded – as this was not stated even as a vague aspiration after IR Refresh 23 and DCP 23, which specifically looked at lessons from the war in Ukraine. The Government thinks our ‘armoured division’ only needs 112 tanks and a very small Attrition Reserve, possibly 15-20 tanks or so.

          • Thanks. That makes sense.

            On the numbers I’m not bothered if we get only 148 if we have a plan. When things start to turn ugly to upgrade the rest rapidly then acquire more to upgrade or build new.

            Of course its not that simple Russia in WW2 built a lot of tanks but couldn’t use them because it had not built trucks to transport men, ammunition fuel, food etc. American and British ended up supplying these a long with huge volumes of other items and equipment, only then could the Russian army advance.

          • Additional question if I may. If RBSL could fit the C3 turret, Trophy, a new power pack and transmission to the C1 just where would that tank rate in your opinion. Let’s assume the c1 has just rolled off the productionl line. Its a bit of fantasy tank fleet question.

          • As our American friends might say it sounds like it might be a bit like putting lipstick on a pig.

            There is such a huge difference between CR1 and CR2, relatively little commonality, and CR2 is the base for CR3. It would take a lot of effort to properly work out how your hybrid would pan out.

            Assuming that your mix is doable, it is easier to assess whether there are any weaknesses by retaining the CR1 hull albeit upgraded by better (CR3 standard) power pack and transmission. The biggest issue would be below-par hull armour but that could be offset by add-on TES armour. The suspension units would be sub-par, as would I think the track. Perhaps modern replacements might easily fit. The hull interior would have to be modified to stow single piece 120mm smoothbore rounds (as does the CR2 hull interior).

            Who knows – it might just make a fair tank, less good than CR3 but better than standard CR1. It would be an expensive and time-consuming conversion, that’s for sure.

          • Thanks for that. Gives a good perspective it doesn’t sound like a good option. Like you say the details are where it would likely fall over. We’ve seen some very cobbled together armoured vehicles from Ukraine and Russia. If we don’t get our act together we’ll likely end up doing the same.

          • Your approach certainly caused pause for thought. By having a very small equipment inventory and mostly unmodernised – then radical solutions need to be explored that could be implemented quickly if WW3 loomed.

            A warfighting division with just 112 tanks is barely credible, especially as the Attrition Reserve (15-25?) will be so small.

          • Just read a Dive story with pictures how Jordan placed 2 chieftain tanks in the Red Sea for a diving experience they look the business

          • Forces Net on Forces News Chal 3 off to Germany for final trials one thing mentioned in the write up is the weight of the Chal 3 could it be a hindrance write up has a few Phots of the Chal 3 Farouk

          • But Farouk, that would mean we had a massive tank capability gap for 5 years. Surely the politicos are not that dumb? (sarcastic comment, obvs). Especially as General War is possible/likely/highly likely?

    • 140 I would stop being “really excited” and start reading some history books… They probably don’t know what books are but hell it’s just a bloody dream…. From the army to the navy and the RAF, God help us.

    • Despite IR Refresh 2023 and its associated Defence Command Paper which were commissioned to identify lessons from the war in Ukraine, Shapps saying that we are in a pre-war era, many European countries leaders saying we are 3/10/20 years from General War with Russia, General Sanders having consistently said the army is too small…. MoD remains committed to just 148 CR3s – two regiments in the field force.

    • Problem is Ukraine has also shown that ‘credible war fighting’ could be very different in the future. We need to prepare for the next war not the last. I doubt anyone though Russia Red Sea fleet would be taking such losses from Done for instance or FPV drone would be knocking out heavy armor on mass.

  2. Hi folks hope all is well.
    As ever I ask you experts to advise me.
    How did the number 148 MBTs ever arise? Obviously we have no land boarder to protect and defend. However, is the number based upon how many have been used in past conflicts, or the likely hood the UK will not have to deploy large numbers as in the case of the former BAOR. Nonetheless, 148 does appear to be a low number. Maybe Ukraine has woken up the government and MOD to review and increase the number.
    Cheers
    George

    • Of the 227 CH2 I believe only around 154 of them were deemed serviceable due to cost of repair being ‘too prohibitive’. 148 number was driven by the Treasury/MOD budget allocation alone, as opposed to any serious review into number required for specific tasks.

      • I don’t know what they mean by ‘too prohibitive’, other countries like the US and Germany would manage to get the job done. Maybe what they mean is the closure of the Vickers factory has left us without the means to refurbish stressed hulls?

        I don’t understand the MODs way of thinking, If you have an asset as good as CH2, surely it is worthwhile to continuously upgrade rather than scrap them. It is criminal that 159 were so quickly disposed of.

        • That’s why As90 is going there’s been no upgrades or refurbishment since it came into service it’s criminal really what’s happening to our armour

          • True. The Braveheart upgrade for AS90 would have been excellent, but it was dropped because some South African ammunition was not up to scratch! Well, buy some ammo from elsewhere!
            Even the mighty and modern K9 cannot fire 3 rounds in 10 seconds as AS90 could.

          • Yes I was at the rsa when brave heart was there . There is enough As90 still to equip 2 units you would think an upgrade would have been cheaper than a dozen trucks with turrets on that can’t even use nato propellant and has no manual operation if the automatic systems fail it’s a joke

          • There was money earmarked for the Braveheart upgrade and the Contract had been awarded in 1999, ie over 20 years ago. I understand it was cancelled because the South African ammunition mooted did not match the new IM remit – but surely we could have got IM ammunition from elsewhere?

            “BAE Systems was awarded a contract to upgrade 96 of the British Army’s 179 AS90s with a 155mm / 52-calibre extended-range ordnance / modular charge system (ERO/MCS). The upgraded AS90s were expected to enter service in 2003, but the programme was halted while a system study was being conducted”.

            The upgrade at £75m for 96 guns was very inexpensive. With further upgrades over the years Braveheart AS90 would have been more than a match for the Korean K9 Thunder (which so many want the British Army to have next) and better in at least one regard – AS90 can do burst fire of 3 rds in 10seconds (K9 takes 15 seconds and the Koreans found it impossible to achieve 10s).

            You are perhaps in a minority to be critical of Archer but I follow your reasons, although I understand that it can fire NATO propellants as well as the unique type you mention.

          • It would be interesting to see how archer can remove individual increments to adjust the propellant charge in its magazine system I work at the school of artillery you won’t find many in favor archer and would rather upgrade As90 or purchase K9

          • Fair point. I doubt a highly automated system can adjust bagged charge increments. Its not a perfect sytem. We should have upgraded AS90 to Braveheart spec years ago – it was a very cheap job – just needed to find the right IM to go with it.

            With further incremental upgrades it would be as good if not better than K9 – even the original AS90 has a quicker burst fire rate.

        • A quick glance at MOD procurement policy shows remarkable uniformity. Along the lines of:- we’re enamoured by the Rolls Royce, but cannot afford the associated running, servicing and inevitable repair costs. So we wait a bit i.e. gap, before being enamoured by the next…….’Think’:- Mr Toad. 🐸📯📯

      • About 2 years ago all the Challengers were transported to Vickers Elwick site now Pearson Eng. for an indepth inspection and they were better qualified than anybody as they probably had skilled personnel with original build experience from the 90,s and the Titan and engineering vehicles from the 2000,s. That doesn’t meen though that they didn’t have an arbitrary figure in mind though and were just going through the motions.
        As you’ll know Pearson are building the turrets and are now part of Raphael so will be well placed to integrate Trophy. Also they provide the army’s mine clearing equipment as well as THE USA, s Breacher kit which they seem to think is their’s and are are always crowing about.

      • Does the estimate of 154 serviceable CR2s include or exclude the 14 provided to UKR? Would explain the 140 statement in the article. Alternatively there could be 8 prototype/trial CR3s. 🤔

        • I have the figure of 157 tanks (not 154) being available for operations, as reported to the UK Defence Committtee on 8 March 2023 (link to follow). That is a very, very good figure, especially for an old unmodernised vehicle.

          When I was in REME we aimed for 70% of key equipment to be available at all times, rising to 90% after 24hrs concerted work with spares being available.

          Given the date of the Committtee meeting then the 14 tanks for Ukraine would have not been included as they had already been sent and the report was about tanks for the British Army – so it would have been 157 tanks out of 213 being operationally fit.

          Perhaps there are 8 pre-production CR3s which will later be raised to the production build standard and added to the 140. We are getting 148 tanks, a miserably small number. (I had better not bang on about the heady days of 900 Chieftains and four armoured divisions when I joined the army!)

          • Morning Graham, back during the heady days of BAOR, I believe we rather hoped the Warsaw pact would be gentleman enough to give us three months notice of war, so we could scramble about calling up reservists, repairing Armour and getting the logistics taps turned back on, in order to get match fit….

          • Thanks John. The Russians effectively gave us all plenty of notice they were planning to invade Ukraine – about 11 months notice!

            Wiki: “In March and April 2021, prior to the 2022 Russian invasion of Ukraine, the Russian Armed Forces began massing thousands of personnel and military equipment near Russia’s border with Ukraine and in Crimea, representing the largest mobilisation since the illegal annexation of Crimea in 2014.[37][38] This precipitated an international crisis due to concerns over a potential invasion. Satellite imagery showed movements of armour, missiles, and heavy weaponry towards the border.[39][40] The troops were partially withdrawn by June 2021,[41] though the infrastructure was left in place. A second build-up began in October 2021, this time with more soldiers and with deployments on new fronts; by December over 100,000 Russian troops were massed around Ukraine on three sides, including Belarus from the north and Crimea from the south”.[

          • A fair point but we did have four armoured divisions in place (three after 2 Div was moved to UK in 1982), and we had all recced our initial OPLOCs. All kit at least at 70% availability. Ammunition well forward in depots etc. Restrictions on numbers allowed back to UK on leave/courses. Many major exercises held – CPX, CFX, FTX – with TA units. Readiness tested by ORTs (Ex Active Edge) ie crash out exercises. NEO plans made to move dependants home etc.

            We don’t have all the elements mentioned above today.

            I don’t think Russia could invade a NATO country without some indicators being flagged or at very short notice. Ukraine had 11 months notice of Russian troops massing on their border.

          • 900 Cheftains, how many we serviceable? I remember the L60 and H30 cyclinder liners could anything so simple be made some complicated

          • I could not guess how many of those 900 Chieftains were servicable at various times from 1966 (ISD) – but it helped that the tank was regularly base overhauled and also upgraded (not the same thing).

            The L60 Powerpack was certainly an issue especially in the early days. A pity that multifuel was forced by NATO at which point RR withdrew from the process, and we ended up with a Leyland unit, developed from a bus engine I believe.

            You are right about the cylinder linings being an issue – they were pressure fitted and coolant leaks within the cylinder block were common, causing white smoke to often billow from the exhaust. In the late 1970s, engine design changed with the introduction of Belzona which was used to improve the lining seals. 

            Still, reliability was never ‘up to German standards’. REME guys and tank crew worked all hours to keep availabilty levels up.

          • I remember the company who used to.make the L60 cylinders. I visited them a couple of times they constantly had orders for them. The liner itself was a good piece if engineering but complex with spines and ports machine into it. Next to RR or Volvo liner it looked over engineered though. Like you say the nature of the unit being multi fuel unit.

          • GM,

            Thanks for the info. Based upon your previous responses/past experience, should presume that the balance of CR2s (213-148=65), will be scrapped after completion of CR3 conversion contract, regardless of condition?

          • Not necessarily, they might be donated to museums, or put in storage facilities (a few old CR2 hulls are currently rusting in storage), or they’ll be expended as targets, or used as training aids.

          • We don’t keep kit for long after it has been formally declared ‘Obsolete’. We don’t have the space or the money required to do that.[It’s incredible how many people think we must have lots of Chieftains or CR1s sitting in a shed at Ashurch ready for WW3!]. Obsolete kit gets disposed of ASAP, regardless of condition.

            Disposal priorities are 1st – try to sell (usually at auction); 2nd – gift the equipment; 3rd – scrap (last option, worse choice, as it generally costs you to scrap something).

            [I disposed of the CR1 tank fleet as just one part of a wider job]

            Gifting includes (as Dern says) donating tanks to: friendly impoverished and desperate countries (Ukraine); to museums; to a few units as gate guards; to specialised units (Shrivenham, dstl) as an R&D platform; to REME Trg Org Lyneham as recovery hulks; to various ranges as targets.

            BTW, we have more than 213 CR2s – just that only 213 are on the active list – ie assigned to a role.

          • Apologies, but wouldn’t any sentient being realize the value of attrition/war reserve stocks of high value equipment? Could it really be that expensive to provide environmentally controlled storage and minimal maintenance for high value equipment? The Yanks and the Orcs have embraced that concept.

          • We have always had Attrition Reserve stocks (used to be called War Maintenance Reserve, WMR) of in-service high value equipment. In the army area that exists for AFVs and artillery, but I am not sure about other equipment, such as soft-skinned vehicles, small arms etc.

            As I said we do not hold Obsolete equipment (equipment that has been formally declared ‘Obsolete’) – that kit is disposed of ASAP by sale, gifting or scrapping in that order (scarapping is a last resort, done only if sale or gifting does not fully do the job).

            Hence (taking just a tank example) that is why we have no Centurion, Chieftain or CR1 tanks in storage for future war use. They are all Obsolete, out of service and are long since gone.

            Tank example. Of course we do have a number of CR2s in the Attrition Reserve as that is not an Obsolete equipment (far from it, it is in-service). In a time when we had 386 CR2s (that was the number originally ordered and delivered), then that Attrition Reserve would have been impressively large (for the UK!), even allowing for there being then more than 3 armoured regiments (tank battalions).
            Now that we have only 213 active CR2s, following Cameron’s austerity budget cuts of 2010, then the Attrition Reserve of CR2s is much smaller, and based at the vehicle depot in Ashchurch.

            At Ashchurch there is also the Repair Pool – a pool of equipment for a unit to draw from to replace a CR2 that is away for a lengthy time on Base Overhaul. In extremis (General War) the Repair Pool could be offered up to bolster the Attrition Reserve.

            The British Army has had use of some MoD Controlled Humidity Environment (CHE) hangers for vehicle storage for many years (at least 25) – and may even have been a CHE pioneer.

            There is some CHE hangers at: the vehicle depot in Germany (Athlone Barracks, Paderborn and/or Ayrshire Barracks, Mönchengladbach); at BATUS in Canada; and some at Ashchurch (more is being built there under a large modernisation plan).
            Of course only a percentage of kit gets stored in CHE (taut budget) and many are parked up in old style sheds.

            My mind boggles at the notion of keeping Chieftains (1950s design) and CR1s (1970s design) for war use in the 2020s and beyond. Clearly the Orcs keep kit that old in storage for use in a major war – but how many western armies do?

          • Morning Graham, is there any news on if these Ch2s have seen any action and success? Were they able to retrieve the damaged Ch2? Wonder if the UK would ever buy any light tanks, like Ascod based UK Brooker or uparm a Ajax or Boxer with Cockerill 105/120?

      • 154 out of 227 being available for use (68%) is a fairly good figure for old kit. When I was in REME our target was to ensure that 70% of key equipment were available, rising to 90% after a solid 24hrs work with spares being available.

        The CR3 programme does not require donor tanks to be absolutley perfect in every respect but they do have to meet an acceptable presentation standard. I understand that tanks go through something akin to a mini-base overhaul before being presented to the RBSL CR3 build line.

        Correct that the very small 148 figure would have been arrived at as a consequence of financial constraint.

        • Just curious Graham, considering the thick armoured hull of a Challenger 2, surely unless it was hit by an MBT numerous times, or accidentally dropped out the back of a C17 / driven over a cliff etc, it would be perfectly capable of rebuild?

          The hull doesn’t twist, corrode or have crumple zones. They simply endure.

          The Americans are still factory rebuilding and upgrading early 1980’s vintage M1A1’s to the latest spec after all.

          Am I missing something, or is there a reason a Chally 2 would be incapable of rebuild?

          • Hi John,
            Back in the day, for as long as I can remember AFVs (including MBTS, obvs) had a periodic Base Overhaul (BOH) done by 18 Base Wksp REME at Bovington or 23 Base Wksp REME in Germany.
            Roughly every 7 years but it depended on mileage as well. Tanks were received at the Bse Wksp with all loose CES (incl jerricans, shovels etc) and documentation. CES was checked and stored. Everything was stripped off the vehicle and sent down refurb lines – or was replaced. Hull was pressure washed, all welds checked for cracks and rewelded if required.
            Vehicle was then built back with mix of refurbished and new replacement assemblies, sub assemblies and components. All mods outstanding were done including some major ones. Vehicle was resprayed. Docs updated, strike plate stamped, CES fitted. Returned to a happy customer (who had stood the loss with a tank drawn from the Repair Pool) as good as new.
            But it was very expensive.

            Fast forward – 23 Base closed as the army started to draw down in Germany. 18 Base renamed ABRO Bovington. A quicker more affordable but equally effective overhaul process was implemented called Base Inspection and Repair (BIR).

            Fast forward some more – Babcock now runs the base workshop at Bovington. This after my time so I don’t know what they do – BOH, BIR or no equivalent periodic very thorough refurb?

            A handful of tanks would not be put through BOH or BIR – if they had a major underlying problem – a distorted hull or maybe a burnt out hull and turret interior. But few and far between, very rare. It must be well over 97% of tanks that could not be refurbished and upgraded. Missing equipment or parts is not necessarily a bar to a CR2 getting the CR3 conversion treatment – depends what it is. There will be a stated minimum acceptable presentation standard that sets this out.

            Upgrades – a somewhat different subject. As mentioned mods were embodied in-house at BOH or BIR. Very major upgrades would be done more often at the OEM. Look up Chieftain on Wikipedia – it had loads of upgrades and each one caused the tank to be assigned a new Mk number.

            For some reason this Upgrades regime did not happen for CR1 or CR2. Neither were substantially upgraded by the manufacturer. A crying shame. I am envious that other countries (US, Germany) do frequent significant upgrades to their tanks – and we dropped the ball.
            The CR2 LEP (now CR3) programme puts right decades of neglect and does all the upgrades in one fell swoop rather than incrementally throughout its life. But the cost and the time to do it is high – one reason the numbers have been limited to 148.

          • GM,
            Hmmm…rather the case of ‘pay me now, or pay me later,’ or alternatively, ‘penny wise, pound foolish.’ Do you presume the genius responsible for the change received a promotion and/or bonus? 🤔😉

          • There is an absolute obsession with contracting out services (standard arrangment or a PFI) that used to be done in-house and very well. Once, on this site, I listed all the ones I knew about and others added to the list.

            The first contractorised operation that I recall being officers’ and WOs & sergeants messes becoming contractor operated – must have been about 30 – 35 years ago. We all moaned about it based on the numerous disadvantages we saw as ‘customers’.

            Its not just soft backroom support areas either – army recruiting is in the hands of contractors, provision of much of the tank transporter service and much of the air-air tanker service are contractor operated. It’s totally mad. When contractors cock up as in Capita with army recruiting, they are rewarded by a renewed contract when the first one expires.

    • Two armoured infantry brigades is all we will have under future soldier, each tank regiment has 56 tanks and the rest are spares.

      Given the entire program is only costing £800 million I really think we should be looking at procuring well over 200 even if we just keep them sitting about spare.

      Ukraine shows how quickly you can loose tanks and how crews normally walk away from loosing a Challenger tank unscathed.

      Replacing main battle tanks is nearly impossible, all of NATO has struggled to get 300 to Ukraine.

      Much the same argument for typhoons in my opinion, you now need a lot more platforms than trained crew.

      • The rest (36 tanks) are not all ‘spares’. Some will be for the Trg Org (RAC and REME) which will be in near-daily use, some for the Repair Pool and some for the Attrition Reserve.

        Fully agree we need more than 148. We had 386 CR2s ordered and delivered for the post-Cold War world.

          • I had not heard that proposal. Tank killers or Tank Destroyers (TD) have some merit. They augment MBTs when they are in short supply and cost a lot less to buy and operate than tanks. They can be useful for flank protection. Most now think of a TD as being a tank cannon on a wheeled chassis, as would be the case with a Boxer TD, but they can be ATGWs on tracked chassis (as was CVR(T) STRIKER) or wheeled chassis.

            Given that we will only have 2 armoured regiments then Boxer TDs would be useful to augment this meagre number of tanks.

          • Thx. I’ve lost the link where I found the reference, which was at the end of a list of proposed new Boxer variants. Sounds like it would be a practical way of augmenting our tank numbers, and if it used ATGWs might be relatively quick to implement.

          • CVR(T) STRIKER was a great piece of kit – a Tank Destroyer with 5 long range Swingfires in launcher bins on the roof and 5 reloads inside. Was withdrawn years ago and never replaced. Criminal!

          • Looked it up on wiki; as you say, smart piece of kit. Obsoleted by man portable Javelin I guess. Looking at Ukraine I would say we would want to replace it. There is a bigger choice of missiles these days; and platforms too – Boxer or Ares maybe, even Bulldog 🙂

          • Except that we didn’t mount 5+5 of the longer range Javelin on a small, nimble, tracked, armoured chassis!

            The platforms you mention are inferior to the CVR(T) platform on the grounds of size, weight, signature, supportability and cost.

    • Tank regt 1: 56
      Tank regt 2: 56
      Field Training Sqn: 20
      Trials and Phase 2 recruit training: 16
      War reserve stock: 0
      Reserve tank regt: 0

      = 148

      Tank regts have 3 sqns of 18 (4 troops of 4 + 2 at Sqn HQ) plus 2 at RHQ.

      On paper, 148 being converted to Chally 3 standard leaves 65 Chally 2s in reserve. But apparently only 17 or so of these are serviceable.

      • Otherwise known as insanity….going down to 2 regiments is foolish, removing any attritional reserve is profundity insane or criminally negligent…..what is worse is we will not even be able to build any replacements…so if for some reason we say lost 20 or so we could not even maintain the 2 regiments and would be forces to move to 1 regiment or buy a different MBT as a replacement….insane.

          • I think UK should face the fact that the voters culture don’t care much for defence and in such circumstances what matters is the minimum the nuclear deterrent and Royal Navy/AF.

            The 2 brigades are more political then military support.
            Basically Brigade 2 being the replacement of Brigade 1.

      • Not sure where you get some of those figures. What and where is the ‘Field Training Sqn’?

        An unserviceable tank may well be able to be presented to RBSL for conversion to CR3 – depends what the issue is.

        • Field training sqn is in Suffield (BATUS), assume now moving/moved to Sennelager. It has/had 20 Challys, so a full squadron and two in the garage.

          You asked before about the trials and training unit at Bovington. It had 22 tanks when we had 3 Chally regts, gather it is 16 now.

          Does it include REME, attrition, etc? – haven’t a clue. I would assume they are included in the 154 serviceable figure, it becomes a bit academic if they aren’t serviceable or MOD is unwilling to spend the necessary to make them so.

          • Thanks Daniele

            For the benefit of other readers, CABRIT is the operations name for the British troops in Estonia, currently a battle group of c 700-900 troops (an armoured infantry batallion of close to 600.plus a Scimitar or Jackal recon squadron and other small combat support or combat service units, the latter being transport, supply, REME recovery/repair and medics).

          • Thanks mate. I had not heard the term Fd Trg Sqn before to describe the BATUS tanks, but then I did not ever serve there and I have been out of the mob for 15 years.
            Whilst ‘the User’ makes a case for the equipments they need, invariably that is cut down by politicans/HMT. The number of tanks that are procured are categorised as for: the Field Force (ie the armoured regts); the Trg Org; the Repair Pool; the Attrition Reserve – the latter two being held in Ashchurch.
            Army HQ may want to play musical chairs with the Field Force allocation to fit in with Whole Fleet Management or for other reasons, thus not all 56 tanks might sit with an armoured regt in peacetime and some are held in depot in CHE and some might have been sent to establish the BATUS fleet.

            However it won’t be the case that there isn’t a Repair Pool (not a REME thing at all, it is a pool for units to draw on if they have lost a tank or two to the Base Overhaul programme for instance). It won’t be the case that there isn’t an attrition reserve – that is provided for and very necessary. There will be CR2s on the active list (213) in Ashchurch – Repair Pool and Attrition Reserve – plus those tanks on the inactive list.

            As for the tanks deemed not operationally ready in that March 2023 snapshot report (213 minus 154) – it is normal jogging that not every single piee of kit is available all the time. Typically about 70% of the tanks are ready to deploy and 30% are not. It does not mean that MoD is stopping those 30% from being rendered fully serviceable – they will be unserviceable generally because of a (temporary) lack of REME labour or spares. It does not mean they are fit for the knackers yard and should be scrapped and/or that they could not be converted to CR3s (if money permits).

      • Regiments going down to 50 I believe, but I can’t remember who told me that now…..

        They will no doubt claim

        “it’s radically more capable than Chally 2 and more reliable, so we only need 50 per regiment”

        “Modern synthetic training negates the need for conventional training to a large degree, so the 36 combined training fleet can be reduced to 20”.

        Leaving 28 in reserve.

        That’s the sort of PR spin bullshit we can expect to make the numbers make sense.

    • Lack of strategic planning basically.
      During BAOR we had something like 600, because we had an idea what we were doing.

      Then the peace dividend kicked in with spreadsheet management.

      Good to see we are actually doing something, but 148 is the derivative if what was left of the original C2 that could be upgraded.

      It would be nice, given we always learn the lessons – ahem – that we would build a few more, given recent learning opportunities.

    • Because the A2020R review reorged the army to 2 Armoured Regiments down from the 3 currently.
      If we only plan 2 Regiments, we don’t need 500 Tanks. And we only have 2 Armoured Brigades to put them in.
      We don’t need 500 Tanks, but we SHOULD be retaining around 200 as currently to keep a 3rd regiment in a 3rd Armoured Brigade.
      That is what is undermining 3 UK Division.

      • Hi Daniele,
        I well remember that once we had some square (2,2) brigades in the standing Orbat ie brigades comprising 2 armoured regiments and 2 AI or Mech battalions.
        No rule says you only have 1 armoured regt per brigade – 7x was a 2,1 brigade in the first Gulf War.
        Apologies, I am sure you know that!
        Historically it has been unusual for an armoured div to have fewer than 200 tanks, then there are the other tanks needed for Trg Org, RP, Attrition Reserve- perhaps we should have 227 CR3s!

        • Morning Graham. Yes, in BAOR some Armoured Brigades had 2 Armoured Regiments, others only 1.
          Indeed, we need extra for the rear echelons you mention.
          Which is why I mentioned around 200. The 227 now would be fine for the current army size we can man and equip with the money available.
          That 3rd Reg needs to be retained and with the delay to Ajax I’ve not given up hope.

      • I would put the requirement at closer to 400.

        3 regular regts is, as you say, really the minimum. Put one in Germany one in Estonia and one in the UK – as we should be doing – and it becomes prettyy clear how thin our tank numbers are.

        That’s 168 operation tanks.

        The case for equipping the reserve tank regt with tanks (they are currently individual reinforcements.for the regulars) is obvious. 44 would be enough in peacetime , to be reinforced by a regular squadron in wartime to bring the regiment up to strength.

        That’s another 56.

        We should have a squadron forward in Poland as part of a NATO brigade whose job it is to keep the narrow land corridor from Poland to the Baltic republics open. We currently have a recon squadron there backing up a US National Guard squadron but that is a very small force for the job.

        That’s another 20.

        Then we nèed enough for the training and trials units.

        That adds 42.

        Total 286.

        Now add a minimum 25% attrition/maintenance/war reserve – far too small really – and that brings the total to 357.

        That probably about the minimum number we need in peacetime but we’d need to he able to ramp up production pretty quickly.if war loomed.

    • Our not having a land border has never been much of a factor. We invented the tank for expeditionary warfare (WW1, their use overseas in France) not for defence of the homeland. We require a significant number of tanks for deployment to the continent for NATO defence – and for ‘wars of choice’ with Allies (usually USA ie Gulf War 1 and 2).

      A careful review of the requirement for a post-Cold War army led us to order just 386 tanks in the early 90s (down from the 435 CR1 order of the late 70s/early 80s).

      We deployed 220 tanks in the first Gulf War (CR1) and about 120 in the second one (CR2) .

      So 148 reflects defence cuts not military requirement. Two armoured regiments totalling 112 or 116 (depending on T56 or T58 regiment), and the very small balance split between the Training Organisation and in storage as both Repair Pool and Attrition Reserve.

      IR23 and DCP23 Refresh looked at lessons form the Ukraine war, and concluded (incredibly) no change to the 148 number!

      • Ironically Graham, the Options for Change review was apparently to size the Armed forces for a post cold war future….

        We have of course gone ‘dramatically’ below the options for change numbers, right across the board, so much so that recovering to the numbers hypothesised in that review, is now utterly beyond us and a pipe dream.

        Oh, and we have a new Cold War and a world situation that’s arguably more dangerous and volatile than the early 1980’s… And getting more unstable by the week.

        But, not to worry, our politicians have a grand plan I am sure…..😂😂

        • I can visualise the dull interchange Starmer/ Sunak, coming off a plane at Heathrow, waving a piece of paper proclaiming “peace in our time” ……

        • Ironic is the word. ‘Options’ reduced the armed forces dramatically – the reg army lost 40,000 men and the TA about 20,000. Plenty doubted the wisdom of such big cuts at the time but the logic of reducing forces when the monolithic threat from the Warsaw Pact had evaporated, seemed inescapbale. The world was going to forever be a safe place!

          Then within weeks of the Options review (Summer 1990), we start to deploy about 200 tanks, 43,000 troops and thousands of other AFVs (plus the air force) on the Desert Shield part of Gulf War 1 (warfighting in this new peaceful world – who would have thought it!).
          We go on to deploy tanks and other AFVs to the Balkans for much of the rest of the 90s on kinetic operations. Going into the new millenium yet more armoured warfare in Iraq (Gulf War 2, 2003).

          Tanks (and other armour) used in anger many, many times when they did not fire a shot in anger for the 45 years of the Cold War.

          The cuts since Options are not because the threat has reduced – they are purely for politicians/HMT to save money time and time again. By most measures the threat has increased since summer 1990 across the globe and especially in Europe and the Middle East – close to home.

          Now we need to rearm and from a very low starting point.

          • Spot on Graham, options for change was far from a carefully considered defence review, it was just a series of savage cuts, pure and simple….

            I had a mate in the Army at the time, he said the only upside of it was an opportunity to get shot of deadwood in the Battalion.

            Each Company suggesting names of folks who had generally been a right pain in the arse over the years, recommended for the Royal order of the boot….

            The RAF in particular, suddenly found itself in possession of a fleet of single role aircraft utterly focused on strike in the European central front, when they actually needed a good solid multi role fighter like the F16 for the post cold war period.

          • The Options for Change defence review did look carefully at the new geo-strategic world, given the dissolution of the Warsaw Pact and the USSR, the emergence of democratic West-leaning countries in eastern Europe and concluded unsurprisingy that significant reductions in our forces were required.
            Total manpower was cut by approximately 18 per cent to around 255,000 (leaving the following strengths – 120,000 army; 60,000 navy; 75,000 air force).

            Troop strength in Germany was halved but not totally axed: a single armoured division was kept in Germany. The RAC reduced from 18 regiments to 10. The Guards went from 8 battalions to 5. Many other Inf bns cut. RA lost 2 regiments. etc etc

            DD/FF cut from 50 to a mere 40

            RAF largely just lost a lot of really old stuff and the manpower that operated and supported it – ageing Bucaneers and ancient Phantoms, Victor tankers and Bloodhound SAMs. But also 3 Nimrods were taken out of service, leaving a mere 32 MR2s! They closed 2 stations in Germany, but still retained 2 other stations there.
            —————

            My point was not really that ‘Options’ was extreme and unwarranted, just that it shocked many service folk, but it was done to match the drastically reduced threat from Moscow and her eastern European Commnits allies.

            However, subsequent defence reviews were just savage cuts to save money and were not justified by any reduction in threat. Arguably the regional threat ‘just beyond our backyard’ actually increased dramatically from 1991 onwards to the present day (Saddam Hussein’s regime ’caused’ two Gulf Wars; instability and civil war in the Balkans caused several British deployments in the 90s; the growth of international and cross-border terrorism led to operations against AQ and their Taliban backers and the Houthis etc – and more recently resurgent and bellicose Russia poses a substantial latent threat to European security).

          • Absolutely Graham, my main issue with Options for change was that it simply didn’t take into account the equipment needed on post cold war period.

            At least the Navy and Army had adaptive assets.

            As said, the RAF totally lacked a capable swing role fighter in shape of the F16/18.

            They had comparatively large fleets of single role strike aircraft, or a dedicated bomber interceptor, in the shape of the Tornado F3.

            A Bae proposal to Japan on the 1990’s of a multi role platform based on the Tornado F3, creating a European Strike Eagle type aircraft, would have been perfect solution for the RAF.

            An F3, with the Sea Harriers Sea Vixen radar, upgraded engines and airframe and able to carry a mixed AA/AG combat load would also have potentially sold well.

            An affordable solution for the RAF of the early 90’s, using airframe assets already owned and a radar already in service.

            Another missed opportunity.

          • I think some would disagree that the RAF was exceptionally badly hit by Options for Change (the defence review of summer 1990 to reset the forces post-Cold War) – as I saai mostly they lost very old equipment (and associated manpower) and did some rebasing, but still kept 2 bases in Germany.
            They had a whopping great 4 types of fast jet – Harrier, Jaguar, Phantom and Tornado (GR1 and F3 ADV). Under Options, they lost the oldest platform – Phantom (a 1950s design) the older ones which had been in service with the RAF for 22 years!
            I am not aware that the RAF ever lobbied for either the F-16 or a F-18, both very different aircraft, due to the loss of Phantom. Did they?
            The Typhoon was being developed and would enter service ajust over a decade later – “On 1 September 2002, No. XVII (Reserve) Squadron was reformed at Warton as the Typhoon Operational Evaluation Unit (TOEU), receiving its first aircraft on 18 December 2003”.
            What was the RAF unable to do with Harrier, Jaguar and Tornado (both variants), until Typhoon came into service…and did it matter…the Cold War was over. The Gulf War happened very soon after Options and the RAF gave a good account of itself with the equipment they had.

  3. “…ensuring it benefits from the best of British engineering and manufacturing, whilst…” we always have to fly the flag on these matters I can understand the motivation but in reality a great deal of the upgrades are of foreign origin and/or supply so to me it always feels a little excrutiating to hear that need to push the line that it’s British excellence at work. Always keen for UK tech to be promoted, too often it isn’t, but far too often too, you have to search for what’s real and what’s simply for effect so you start doubting everything. In the end it’s what is best for the guys who’s lives depend on it that’s important so own it, especially when those promoting ‘Britishness’ are also those who have sold it out over the years by not supporting it.

    • It’s quite insulting how many German and US company’s paint British flags on vehicles. It’s even worse that our military and media let them get away with it.

      Especially when they turn their nose up at armoured vehicles from a British company that seems to be good enough for everyone else.

    • I think its been identified in the chat above they have -“only 154 being cost effective to upgrade”.
      Now you could question the algorithms used to identify ‘cost efective’ as surely if there are 227 hulls available then potentially ALL of them could be upgraded – but obviously ‘capacity/capability/force’ isn’t a metric they considered.

      • As it is my understanding and happy to be corrected. As the Ch 3 just uses the basic hull. The power pack. Drive, suspension and turret are all replaced. I find it difficult to believe every tank cannot be upgraded and given the leap in manufacturing tech. If necessary That new CH2 hulls cannot be fabricated from scratch.
        A patently obvious lesson from ukraine is that 148 is no where near enough,

        • Correct on all you have said and Rhienmettal have said hulls can be built if they are wanted! It’s just been reported that since 2010 £24b has been spent on ALL migrants coming into this country WTF could we have done with that?

          • No it’s not. The editor/founder of this site permits topics about Scotland and its political future – check the current index. So the analogy by Jacko is perfectly legitimate.

          • Money spent because the government can’t process asylum applications , Legitimate it may be but I happen to disagree with it and their have been far more cash wasted by this government, eg HS2 to appease the Nimbies, garden Bridges, Thames airport, Covid PPE procurement

      • I read that 157 were available for operations (back in March 2023), which is normal jogging. Does not mean that c.70 were fit for the knackers yard or unsuitable for upgrade.

  4. So, just to be clear, beyond this the UK has no plans for a British-only designed and produced replacement MBT (i.e. CH4 – and please don’t say Rheinmetall is British).

    Given that in the past the UK has arguably come up with the best tank design in the world, the current threats and unreliableness of other countries and licensing agreements for export, is this a sensible stance by any UK Government?

    • I wish they would invest in a CH4 programme.

      One of the issues is that we don’t have the capability anymore to manufacture heavy armour in the UK. BAE bought Alvis Aickers, closed the factory and shipped the hardware to their swedish facilities decades ago.

      We don’t have barrel making capabilities in the UK, hence germany supplying the turret/gun. And we don’t have a factory capable of making the hulls. So all of this would have to be built up from scratch.

      These days spinning up a new factory and production line would cost billions, and make the unit-cost of CH4 enormous unless large enough orders are placed. No defence company is going to do with without a guaranteed order book of a serious number, and the UK isn’t about to place an order for 1000 tanks.

      What you need is a coalition where 3/4 other countries agree to buy export variants. They will also then want workshare, which is where many joint-european projects fall apart. This could work in other ways. We agree to buy dozen of archers from sweden and they agree to buy CH4. Italy agrees to buy CH4 and in turn supply engines for CH4 or tracks or something like that. Spain we already get ajax hulls from. They could do final assembly of CH4 locally.

      However. The Leopard production line in already running, not sure about the leclerc one – i think it still exists, so the upfront unit cost of the next generation of those tanks is going to be cheaper.

      • True. I agree. However, I would argue that the UK needs a new organisation (separate from the MoD) that is tasked with the responsibility for preserving, nurturing, and developing certain key strategic assets, capabilities, and resources. Included in this would be the ability to design and produce a MBT and other heavy armour and retain IP control. Such an organisation would also help implement common design components to help keep costs down. Sort of similar to the Ministry of Aircraft Production in WWII, but be across a number of sectors (energy, cyber, computing, materials etc.)

        Yes this would cost initially to set up (certainly to get MBT capability going), but there would be a wider benefit to the UK economy and, the UK’s FO should be capable of twisting a few arms for export to close cousins only – especially if we are buying their kit.

    • I think we will be relying on the Shah of Iran to make a re-appearance….. then we can start to design the future MBT’s….. For those of you way too young to know…… the original CH1 was actually built as an Export model for Iran……. Also, It might be of interest that the Invincible Class had an interest from Iran for 3 hulls too……. Also, We and the Americans sold Ships and aircraft to them too…… F14 Tomcats and Vickers Frigates to name a couple…….. Not everyone in Iran is anti West….. there are many who are living under religious repression that still have their own thoughts. Iranians are not our Enemies. It’s just a minority who want to treat us as such…..

      • I think many Iranians might welcome the Shah back given that the 1979 revolution resulted in a theocratic dictatorship.

      • Sure. I am not anti “Persians” at all. I went to poly with shed loads of Iranians just as the Islamic revolution hit. Lovely people (and food). Suddenly they stopped wearing their military uniforms, and a whole bunch of “nutter” Iranian students tried to take over the student union shouting “death to America.” You could see the madness in their eyes.

        By the way I am not suggesting the free and easy export of arms. I am against Typhoons to Saudi for example.

    • We are observors on the Franco-German future tank project. There will be some back room research being done at dstl and maybe QinetiQ. Not sure we are doing anything else on ‘CR4’.

    • I would rather see something British-designed and locally manufactured, even if the company itself is not British, I agree that in the event of a major war supply chain distance matters.

      • To me it is also about UK industrial base and wider benefits to the economy if the world situation means that we need armed forces and need them to have right equipment for the job.

  5. In an increasingly dangerous and uncertain world we won’t have enough tanks to last more than a few weeks in a major conflict. It’s hilarious how they can make those drum beating quotes with a straight face and any sincerity!

  6. So in light of how Labour have taken the knee to its Islamic voting block (these has been a rise of people leaving Labour for future independent Islamic candidates ) I wonder how the next Labour Government will appease it Islamic and lefty voters regards Israeli equipment in British Army service . In the article above Challenger 3 is (supposed to be) fitted with Trophy
    There’s the litening pod, The Uk has been the first to adopt the Litening 5
    Spike NLOS aka Extractor
    Watchkeeper based on the Hermes 450
    Virtus webbing
    The numerous software packages in use
    The Dismounted Joint Fires Integrator (DJFI)
    How about the Israeli bandage
    Lets not forget the F35, will Labour pull the plug on building parts
    The Pakistani MP for Coventry   Zarah Sultana who is on record of Antisemitism (but its ok she said sorry for telling a jew to kill himself on twitter) is pushing a bill in parliament to end all arms deals with Israel. She will be in power this time next year and I will not be surprised at all if they demand that the Government freezes military spending and the money saved to be spent on rebuilding Gaza, seeing as British weapons (in her eyes are responsible for genocide) I dread to think what else these social justice warriors will come up with (Looks at Humza Yousef, the candidate for Welsh labour,  the mayor of London and of course SF in NI)

    My point, are we going to see a Government bite off its nose in which to spite its face regards Israel. On that note a few things invented in Israel which I would love to see these people who demand we boycott Israel stop using:
    Intel chips
    USB pen drives
    Computer firewalls
    Face ID (as used on apple phones)
    Windows XP, Windows NT
    instant messaging
    Amazon Kindle
    Mobile phones
    Sambucol
    Computer printing.

    I cant understand why these people don’t go the whole hog

      • Jacko,
        The thing to note is note about the calls for a ceasefire, is where the pro islamist activists demand we go afterwards. We already see their handiwork in the targeting of anybody who doesn’t support their mindset, be they companies (McDs, Coke Cola, Tescos, Marks and Sparks) MPs where they think nothing of targeting the homes of MPs, Arms companies with nothing to do with Israel . The reaction from Government the Police and authority in general is dont upset them and simply let them do as they please. In other words the rule of the Mob is the way to go. I wear a small enamel union jack on my barbour and I’ll be honest I am waiting for the day some wanker decides to bump his gums in my direction, because I am not going to mess about and argue with them I will simply put that person on his arse. the only thing these people recognise is actual violence and I am more than happy to show these social justice warriors that faroukie is willing to stamp their ticket.

        • Hopefully you will end up in prison shortly afterwards as you deserve.

          While we are chatting: After the Hamas attacks in Oct you claimed a Lesbian and Gay group had endorsed the attacks; I checked and found nothing; I challenged you for a source and you shut up for a few days; After the question and your silence had sat there for a few days others complained and it was all taken down; For the sixth or seventh time what was your source and why have you kept it secret for four months?

          I ask because I suspect you made it up to promote homophobic bigotry and rape a Lesbian and beat up or murder a Gay man by proxy.

          • His claim was posted three days after the attack and was quite explicit about a LBGT group endorsing the initial attack. I checked and there was nothing.

            Since then various LBGT groups have called for ceasefires but a, that was subsequent to his claim and b, a different thing.

            I checked thoroughly, I think he made it up. That’s why for four months he has refused to give a source or reason for keeping shtum.

          • Was that the Article that had 70 posts removed ? ….. I didn’t see what was posted but in the morning, 70 comments had been deleted leaving just 30……

          • There have been several posts like that on here. They tend to be ones where the usual extreme right posters have made various dodgy comments, the debate has become heated, the mods close it down, either on their own initiative or because of complaints.

            I do not think it was one of those. The question stood for almost a week with no reply during which he was active on the site. Then someone complained, perhaps a friend covering for him, and the thread was deleted.

    • There’s some interesting stuff on YouTube re this
      Broadly it comes down to ammunition and supply chain.
      Rifled is good for certain things but has limitations in ammunition it can use.
      Smooth bore still has excellent accuracy, doesn’t wear as much and can handle 120mm from many, many sources.

      It probably makes sense overall to change given the UK production capability for replacement barrels, ammo etc.

      I’d rather we just had 500 of them

    • Barrels last longer.
      Greater variety of ammunition and commonality with many allies
      Better armour penetration with a longer compatible penetrator.
      But
      Lower accuracy at long range when using explosive ammunition.

    • It depends what rounds you fire from it..smoothbore is better for Fin stabilised discarding sabot as the round does not need to engage with rifling and therefore has less friction…which equals higher velocity and more accuracy as well as less barrel wear….the problem is that it cannot fire HESH and the British army had a long standing love of HESH ( high explosive squash head)…really because the HESH was a kill anything round…but modern MBT composites armour is very resistant to HESH so the British army moved to fin stabilise discarding sabot for MBTs and HESH for everything else ( HESH is particularly good against fortifications and concrete structures as well as light armour….in reality a fin stabilised round from either a smooth bore or rifled 120mm is essentially going to penetrate any MBT at all ranges..so it’s a bit academic…but:

      The Thing was no one else in NATO had the whole HESH love…which means everyone else went to smooth bore..so the British army ended up with different fin stabilised discarding sabot round than the rest of NATO which is a pain…soooooooo

      • I found a very detailed analysis online comparing the armour penetration of various tank guns and their accuracy at different ranges. From memory, the L30 was only slightly inferior to the Rheinmetall smoothbore at armour penetration out to 2000 metres. At longer ranges, the rifled gun was more accurate and effective against a wide variety of targets. The main problem of the L30 was the limit on the length of the penetrator that could be used with the separate bagged charge. Using a DU penetrator, the L20 could achieve very similar effects to the longer tungsten carbide rod in the Rheinmetall one piece round.

    • I’ll also add, The Chally 3 needs the Rheinmetall 120mm L55 smoothbore over the Chally 2’s L30A1 rifled gun, to maintain the effectiveness of the main tank killing round, the armour piercing fin stabilised discarding sabot (APFSDS) or Fin for short.

      The L30A1 uses two part ammunition, i.e. the round and the propellent bag. Three part if you include the vent tube initiator. Herein lies the problem. To penetrate modern composite armour you require the Fin’s dart to overmatch the armour in both length and density, with a lot of kinetic momentum to drive it forwards. The dart is manufactured from either a depleted uranium or a tungsten alloy. This allows the dart to punch through lighter steel alloys. However, as the dart punches through it is eroded, so you require a longer length of material to allow it to keep pushing through the tank’s armour. Whereby after passing through the armour, the remaining material bounces around the insides mushing up everything and hopefully hits the tank’s main gun ammunition to detonate it.

      The length of the dart of the L30A1 is governed by how much of it can be held in the barrel’s throat. The round is held by the following combustible propellent bag. The bag is held in the chamber and is of a fixed volume. Therefore to make the dart longer, you need to make space for it in the propellent bag. Which therefore means there’s less propellent to push it out of the barrel.

      The L55A1 uses 1 piece ammunition, so it looks like a giant cartridge case that is nearly 1m long. However, as the propellent can surround the rear end of the dart. The dart can extend into the propellent and therefore be longer. Whilst still containing more propellent than the L30A1 propellent bag.

      A of people will miss High Explosive Squash Head (HESH). However, it can’t use a proximity fuze or programmable timed fuzes. So unlike today’s multipurpose high explosive shells. It can’t really be used against trenches or timed to detonate after passing through a wall. HESH can be fired by a smoothbore barrel, it just needs a slip ring to impart the necessary spin. That ensures it “splats” evenly when it hits the target.

      • So ‘we’ could still use HESH with a smooth bore then? I assume it’s just not cost effective to make them if we are the only ones that use em?
        What changes will need to be made to how we ‘fight’using tanks without HESH…would we lose any capability?

        • Hi Griz, sadly HESH development stopped in the early 90’s. It is simply outclassed, due to modern tank gun HE shell’s using programmable fuzing.

          HESH is predominantly a block of plastic explosive (PE), enclosed in a thin metal or plastic shell. When fired it has to have a low muzzle velocity. Otherwise when it hits the target, it may bounce off. Or the shell fractures too quickly and the PE fractures and splits off. To be effective the PE must firstly stick to the target, but also form a circular “cowpat”. Which means when it detonates the explosive shockwave is maximised over the covered surface area. Which for a non-spaced armoured tank, a large chunk of spall would be ripped off, to bounce around the insides of the tank. On thinner armoured vehicles such as say a BTR. The shockwave can cause either the armour to be flattened and pushed in. Or it can rip off the whole area around the cowpat and explosively force it inside.

          The disadvantages with HESH is due to the mechanics on how it works. The fuze for example must be at the rear of the PE. Which allows the PE time to stick and form the cowpat, before detonating. The thin outer case is necessary so that it can split easily, thereby allowing the PE to stick to the target and form the cowpat. Which means, that it has a small fragmentary effect on a target. Having the fuze buried at the back and within the PE makes it really hard to include a proximity or programmable fuze.

          If we look at today’s ammunition that is available to the Rheinmetall Rh 120 L44/55 guns. There are a number of multi-purpose rounds that combine HE, HEAT, anti-personnel and anti-fortification into one round. Orbital’s Advance Multi-Purpose (AMP) round that has been developed for the Abrams. Merges the High Explosive Anti-Tank (HEAT) with a fragmentary HE shell. By use of clever fuzing it can be used against a multitude of targets, that are programmed in the gun by the gunner. But as it uses a preformed tungsten shell around the high explosive, makes it affective against infantry. But because it has a programmable fuze, this can be timed to detonate when it reaches the measured target’s range. Therefore can be used against Anti-Tank Guided Weapon’s (ATGWs) teams and slow moving aircraft.

          Therefore depending if the MoD buys multi-purpose HE ammunition, such as the AMP for Chally 3’s main gun. The effects should be greater than what HESH can currently provide. But also gives the tank much greater flexibility against the type of targets it could engage.

  7. It’s good that this is going ahead as we really need a tank with an active protection system…but we are buying 100 to few…simply put we need around 250 MBTs, anything less is just BS. We have to have 3 Type 56 regiments…going to two is bonkers…that’s 168 MBTs add on 10% for maintenance pool ( 16 MBTs ) and 10% for training establishments 10% (16) and then an attritional reserve of 100% replacement or one regiment ( 56 MBTs)…that gives you 256….that’s what we need any programme that does not deliver that is flawed.

    • So reading below when Options for Change stated 386 (ish) what happened to generate the difference between 386 and the 256 you mention above…was it merely a reduction of tanks per brigade or were there more brigades back then…or both …or was it something else that changed to cause the resultant numbers reduction….or was it just simply budget?

      • Hi mate. That requires some explanation and an understanding of the various ORBAT and Brigade changes back then…so.

        There were 3 Armoured and 3 Mechanized Brigades in the early 2000s.
        So 6 Armoured Regiments. In 1st,12th,19th Mech and 4th,7th,20th Armoured Brigades.
        19 Mechanized Brigade became 19 Light Brigade in defence cuts, so that got rid of its Armoured Regiment.
        4 Armoured Brigade in Germany became 4 Mechanized and returned to the UK. It, along with 1st and 12 Mechanized Brigades each had Armoured Squadrons withdrawn and those Squadrons replaced by Scimitars in what at the time were called “Medium Armoured Squadrons”
        That I assume goes some way to seeing where those extra Tanks vanished to.

        • So 3 Armoured brigades went down to 2 (4th Armoured became 4th Mechanized)
          1 Mechanized (19th) became Light so lost its armoured regiment.
          The other 3 mechanized (1st, 12th & then 4th) Lost Armoured Squadron).
          Did Mechanized Brigades 1st , 4th & 12th) keep some CH2’s then?

          • Depends on the period.
            Pre 2010 there were 5 heavier Brigades.
            1st,4th,12th Mech and in Germany, 7th and 20th Armoured.
            All had Armoured Regiments. So 5 total.
            After the ludicrous 2010 cuts the army reduced to 3 heavy Brigades – 1st,12th,20th, all in 3 UK Division and now termed
            “Armoured Infantry Brigades”
            All had an Armoured Regiment, so 3 total.
            This remained the situation until the 2015 A2020 Refine review which decided we needed Strike…the catch was/is, one of our Armoured Brigades would be converted and would not need Tanks.
            So 12 and 20 Bdes remain, with the 2 Tank Regiments. A 3rd, the Kings Royal Hussars, is still about because Ajax was delayed and it did not convert yet, even though 1st Armoured Infantry Brigade reduced from armour to the DRSB, but is still due to despite all evidence saying it is a mad idea.
            That is the timeline and I hope it makes more sense. It is difficult to follow and make sense of unless you’re a saddo like me who tracks this stuff. 😄

      • Can’t be 100% sure, but I guess that any prototypes or pre-production versions will be upgraded to production standard after trials and Acceptance and issued to the army as part of the 148.

  8. Given how effective NLAW and Javelin were reported to be at killing heavily armoured Russian tanks in the early part of the Ukraine conflict, has any thought been given to how CH3 would protect itself from an Iranian, Russian or Chinese copy of such systems? Has this also carried over into Ajaz and Boxer design?

    • Good point, I suppose the boffins will be tweaking APS systems to cover a higher arc. and well as increasing the armour up top

      • Look, the challenger maybe brilliant but at that number it would need to take out at least 20 other tanks and survive drone attacks in order for us to win. Hell we dont even have the ammo to take out 20 tanks per tank.

        • Are we talking CR2 or CR3? I guess CR3.

          We will have 112 tanks in the two armoured regiments that Future Soldier give us. How do you estimate we need a 20:1 kill ratio? That they will be up against 2,240 enemy tanks? I hope there aren’t quite that many, just for the British armoured division to take on.

          I had not heard that there will be a shortage of 120mm smoothbore ammo – why is that?

    • So that, in a T56 Regiment, would be 7 or 8 Regiments worth, if you include a reserve fleet for training, trials and attrition.
      We currently have 3, reducing to 2, and there is a personnel shortage….fantasy land I’m afraid.
      Lets just keep the 3 we have, with about 220 Tanks, and spend the money elsewhere.

  9. Sadly there are NO votes in defence, only profits for large corporations and the ability to create local jobs.

    Ukraine has shown that you can be highly effective with relatively low tech weapons. The big problem is that the UK wants be in the Premier League with a Division 2 budget.

    The optics of sending 4 patrol boats to the NATO exercise while aircraft carriers are u/s along with a second Trident missile launch failure makes the UK look weak and incompetent. That is totally unfair to those serving .

    If you are going to speak softy and carry a big stick it cannot break the moment you touch it.

    • Having 2 carriers with planes for just one is plain stupid, ridiculous when we had 3 and planes for all 3 and spares. We dont have a division 2 budget, our budget is way below those of any competent nation, yet we are supposedly the 5th or 6th largest economy in the world, look at Poland, a fraction our economy buying 1000 tanks, Greece a fraction of that having more tanks refurbished than we possess. Part of our issue is that our companies are run by idiots, our politicians arent as experienced and knowledgeable as those idiots and our civil service is employed by the kremlin

  10. I get it, 148 does not seem to be a lot, but the design, structure and capabilities are all tied in to NATO stance. We will never go to war alone. We will play our part, whether it’s with tanks, drone squadrons, ships and boats and even those pesky f35 pilots. Our forces does not need to be large any longer. A war in Europe isn’t like a war in Ukraine. Boats on the ground will be minimal. We will need to defend the skys around us. I would spend more in air defence than land offensive these days.

  11. CH3 is clearly a short to mid term fix for tank needs, based on existing stocks as a hold over. Creating a new tank takes a long time and the key issue is numbers. Making a domestic tank in the low 100s, with associated dev costs and mediocre economies of scale makes the project highly cost prohibitive.

    The Germans recently pulled out of the French program and joined the Italians/etc where there’s less stubbornness. The UK needs to join the Germans or French (French joint programs are hit and miss…).

    Alternatively we can go looking elsewhere, perhaps with a country that has similar requirements. The Japanese Type 10 is 40-48 tonnes with a 120 smothebore compatible with NATO, and Japan are an island like the UK. Makes more sense logistically as the CH2-3 seems to be so heavy it’s best stationed in Germany.

    Personally I think we need to make a smaller, cheaper tank so we can A) have more tanks & B) try to export it to middle powers in Latam, ME and Africa. Japanese export controls would be a problem however.

  12. Poland ordered 1000 extra tanks, Greece is renovating and upgrading 500, how are we satisfied with such a small number when our economy is so much bigger?

    • A better solution would be to give all the Challengers to the Ukraine and let them rebuild them. The Ukrainians have really good mechanical skills which sadly we no longer possess. They can refurbish at a fraction of the UK cost.
      We then replace the Challenger with Leopard tanks which have – by default – become the NATO standard kit.

      • We have 2 carriers, mostly broken down and enough f35s to stock just 1 of them (leaving the other as an undefended target – and that is assuming the RAF dont need the f35s for something else as they are shared (to give the impression we have more than we do they can be given as the planes for the raf and planes for the navy). The enemies we have – russia for sure, china in the very near future would scoff at that handful of submarines, the chances of survival for the single at sea ssbn to the point of launch of its missiles, never mind the chance of survival of the tiny number of missiles involved, regardless of the fact the last to launches have failed miserably means no one, no one at all is going to be even remotely scared of them. It is time to get REAL, the USA has now let down Ukraine on top of a long long list of other people, hell given the fact they look set to elect trump and he is more friends with russia it could be we are facing off against the USA as well! but we can guarantee we cant rely on them. Looking at the rest of europe, Macron in France and Greece have just blocked drone aid to Ukraine, Germany has also just blocked aid, Poland is letting its farmers stop weapons shipments going over the border so we KNOW Ukraine is going to lose because none of the ‘we will stand by you to the end’ western leaders is standing by them, in fact the west has decided to appease putin with Ukraine and we know from the 1930s just how well appeasing a dictator works but no one in power in the west has ever read a single history book, and nor it seems has most of the population.

  13. Bit of a silly question but are the tanks shells stored at right angles or parallel to the turrets walls? Wonder if they would look at a slightly bigger turret to accommodate more shells than the 31? Probably way too late in the process now. And even having an anti-UAV gun/laser mount on the top? Just asking.

    • So generally parrallel, or vertical, but most of the ammo in a Challenger II is in the rear bustle IIRC, so aside from a few ready rounds generally not on the walls at all. The bigger issue is that CR2 uses two piece (technically 3 piece) ammunition, while CR3 uses one piece ammunition, which is what necessitated the redesign of the turret in the first place.

      Remember: More ammunition means you can shoot more but it also increases your risk of joining the Orbital Turret Launcher program.
